    Finding tiny bit of sand in the boot twice now.

    First I like the fact I can take the two layers apart and get the sand off of the outer layer, never see any sand in the inside layer or even between the two layers. SO it has to be getting around the seal, the inner layer seal seems fine but the outer is very thin and has a bunch of ridges that I think may be doing more harm than good letting some sneak by. And yes I am sure everything is lined up correct, greased and clamped down correct by the cage. This time I am going to wait a day or so and retighten the hold down bolt, maybe the outer tinner harder seal takes time to crush and form. All I know is if I ever find any more sand in the boot with this filter I will try twin air to see if it happens again. Maybe I have a boot leak but sure doesn't seem like it at this point. Or maybe it is the new grease I used the last two times from no-toil which every time I clean it that grease has hardened to a wax like crap. I am back to using WP Power Punch grease that I have used for years with all brands of filter and maybe that is the cause of the leak. In 35 years of dune riding this is the only 2 times I have ever had sand in the boot. and it is the only times I have used the Uni-Filter and no-toil grease... Something is wrong! Love the two piece design just no the outer layer seal design... Will post again after next cleaning.

    Works for '05 KTM and '14 YZ 450s

    Originally bought these skins for a 2005 KTM and now I use them on a 2014 yz450. They work good and save you from having to clean the filter after every ride. However, after several uses I noticed small holes appearing.

    Doesn't work at all

    Doesn't stay on, water gets in just as easy, even makes the quad run bad, "flutters"

    It works.

    Why would anyone mess with filter grease when these are available? Works perfectly. If it dosent stick you didn't clean the mating surface properly. They even give you a little extra piece of the material to test the adhesion. Cant go wrong with this. .

    Fit perfectly, I think the filter helps the machine run even smoother than it did before.
